We will start the half marathon on Sunday at exactly 11.00 on the Breestraat in the old center of Leiden at Het Gangetje.


The finish is at the Vismarkt in Leiden, behind the town hall and next to the Rhine, in the middle of the cozy old city.

Time Limit

Your half marathon may take max 3 hours. Exactly 3 hours after the start (net time) the finish closes. If you come in after 3 hours, your time can unfortunately not be registered. If you are outside the timetable during the run, you will be asked to get in the broom wagon. If you will not do that, you run outside the responsibility of the organization.

Everybody is a winner



The maximum number of participants on the half marathon is 6.000, so register quickly.

Minimum Age


The minimum age to participate in the half marathon is 16 years (at the day of the half marathon).

Own drinks

You can deliver your own drinks on Sunday until 9.00 a.m. at the bag wardrobe. Clearly state your start- number and the care station where the drink should be placed. The bottles with your own drinks are clearly visible on the right of the care station on a separate table. Bottles that are not collected will be destroyed. There are care stations on the half marathon route after 5½, 11, 15 and 19 km.

Course record

Nice to know is that the course record of the half Marathon is held by Nathaniel Kipkosgei (Kenya). He ran a nice time in  2011: 01.01.25. The fastest woman ever at the half Marathon is  Edinah Kwambai (Kenya). She ran in 2010 1.10.52. There is a bonus of  € 500,- at the finish for the first runner to improve the course record.

Competition Section

Competition license holders and runners who can demonstrate that they have run faster in 2019 or in 2020 than 1:20 (men) and 1:30 hours (women) are allowed to start in the competition section.We want to check your time, so mention the name of the website where we can find your end time.

The Pacers

This year, again, there are pacing teams in Leiden. Pacers are experienced marathon and / or ultralopers who can run a very flat schedule. Along the way, they drag you through difficult moments and give tips and advice along the way to make your race a success. Following a pacer is for free and you do not have to register. The pacers wear a special yellow shirt and a yellow balloon with the target time. The pacers get together 30 minutes before the start in the starting area at the head of Breestraat.
